Detailed Description

a transport using Unix stream socket

Definition at line 37 of file unix-transport.hpp.

Constructor & Destructor Documentation

UnixTransport()

Member Function Documentation

connect()

void ndn::UnixTransport::connect ( boost::asio::io_service &  ioService, const ReceiveCallback &  receiveCallback  )

overridevirtual

asynchronously open the connection

Parameters

ioService	io_service to create socket on
receiveCallback	callback function when a TLV block is received; must not be empty

Exceptions

boost::system::system_error

connection cannot be established

Reimplemented from ndn::Transport.

Definition at line 77 of file unix-transport.cpp.

References ndn::Transport::connect(), and NDN_LOG_DEBUG.

close()

void ndn::UnixTransport::close ( )

overridevirtual

Close the connection.

Implements ndn::Transport.

Definition at line 106 of file unix-transport.cpp.

References NDN_LOG_DEBUG.

pause()

void ndn::UnixTransport::pause ( )

overridevirtual

pause the transport

Postcondition

receiveCallback will not be invoked

Note

This operation has no effect if transport has been paused, or when connection is being established.

Implements ndn::Transport.

Definition at line 115 of file unix-transport.cpp.

References NDN_LOG_DEBUG.

resume()

void ndn::UnixTransport::resume ( )

overridevirtual

resume the transport

Postcondition

receiveCallback will be invoked

Note

This operation has no effect if transport is not paused, or when connection is being established.

Implements ndn::Transport.

Definition at line 124 of file unix-transport.cpp.

References NDN_LOG_DEBUG.

send() [1/2]

void ndn::UnixTransport::send ( const Block &  wire )

overridevirtual

send a TLV block through the transport

Implements ndn::Transport.

Definition at line 92 of file unix-transport.cpp.

send() [2/2]

void ndn::UnixTransport::send ( const Block &  header, const Block &  payload  )

overridevirtual

send two memory blocks through the transport

Scatter/gather API is utilized to send two non-consecutive memory blocks together (as part of the same message in datagram-oriented transports).

Implements ndn::Transport.

Definition at line 99 of file unix-transport.cpp.

create()

shared_ptr< UnixTransport > ndn::UnixTransport::create ( const std::string &  uri )

static

Create transport with parameters defined in URI.

Exceptions

Transport::Error

incorrect URI or unsupported protocol is specified

Definition at line 71 of file unix-transport.cpp.
